While pregnancy is an exciting time for expectant mothers, it can pose extra health challenges. This is especially true regarding dental health.

Because of hormonal changes that naturally occur during pregnancy, your teeth and gums are at higher risk for dental disease. These changes can increase cravings for carbohydrates, particularly sugar. Increased sugar consumption feeds bacteria found in dental plaque, which is most responsible for tooth decay and periodontal (gum) disease.

Hormonal changes can also make your gums more susceptible to infection. Conditions may be favorable for a form of gum disease called pregnancy gingivitis, which can begin as an infection in the surface layers of the gums. But like other forms of gum disease, pregnancy gingivitis can advance below the gum line and lead to serious health consequences.

Because of this "pregnancy effect" on your teeth and gums, there are some things to which you should pay heed while you're expecting. First and foremost, keep up a daily regimen of brushing and flossing to remove accumulated dental plaque. You should also control your sugar intake to minimize bacterial growth that can cause disease.

It's also important for you to continue regular dental visits during your pregnancy. Your dentist will monitor your dental health and initiate treatment if you begin to show signs of disease. Besides professional cleanings, your dentist may also prescribe antibacterial mouthrinses to combat bacteria.

As far as dental procedures, essential treatments like fillings, root canals or extractions are usually considered safe to perform during pregnancy. But elective treatments of a cosmetic nature are best postponed until after your baby's delivery.

One last tip: because of the higher risk of tooth decay or gum disease, be on the lookout for any abnormal signs in your mouth. This includes spots on the teeth, tooth pain or swollen, reddened or bleeding gums. If you see any of these signs, see your dentist as soon as possible.

Your teeth and gums are indeed at risk for disease during pregnancy. But daily hygiene, regular dental care and attention to signs of disease can help keep that danger at bay.
